出售化工设备配套重油泵GR70SMT16B
故障一:真空压力表的指针剧烈跳动,泵噪声振动大。
发生汽蚀。
1、吸入管路不密封,有空气渗入
检查吸入管路的各连接处,拧紧螺母或更换已损坏的垫片
2、进口过滤器堵塞或吸入管路有阻碍物
清洗过滤器或消除阻碍物
3、介质粘度太大
提高介质温度,使粘度下降,或更换介质
4、泵转速高
降低转速
5、泵排出回流入油箱内的介质所混入的空气未很好排除,随介质一起吸入泵内
检查油箱内是否有钻许多孔的隔离挡板和挡板是否完好,或对介质升温,使空气易从介质内上浮排离

机械密封安装时:
1、要十分注意避免安装中所产生的安装偏差
(1)上紧压盖应在联轴器找正后进行,螺栓应均匀上支,防止压盖端面偏斜,用塞尺检查各点,其误差不大于0.05毫米。
(2)检查压盖与轴或轴套外径的配合间隙(即同心度),四周要均匀,用塞尺检查各点允差不大于0.01毫米。
2、弹簧压缩量要按规定进行,不允许有过大或过小现象,要求误差2.00毫米。过da会增加端面比压,加速端面磨损。过小会造成比压不足而不能起到密封作用。
3、动环安装后,将动环压向弹簧后应能自动弹回来。
